SYSTEMS AND METHODS FOR SYNCHRONIZING TIME SOURCES WITHIN A PROTECTION ZONE OF A DIGITAL POWER SUBSTATION

摘要

Provided is a system for synchronizing time sources within a protection zoneof adigital power substation. The system includes a global time source, aprocessingcommunication network, an electronic, and a process unit. The process unitincludes atime source configured to receive and process data packets, which include afirst time signaland first time quality from the global time source and the second time signaland secondtime quality from the electronic device. A time source of the process unitsynchronizeswith a protection zone master clock within the electronic device where thefirst time signalis unavailable or the first time quality of the global time source is degradedbelow apredetermined threshold. The embodiments also include a method forsynchronizing timesources within a protection zone of a digital power substation.
